Hi Murph
Sorry not popped in for a while, been updating my site and doing VERY big renders for the project, sand has proved to be a tiresome bugger to get right!! As with the lighting for desert environments. Think I've downloaded half the desert images off the web for reference!!
Your pic is cool man, I had to check the zip file, dont do rar ones Im afraid. Maybe bend the Sharkodile a bit at the neck upwards, posewise, so it will look like its homing in on its prey.

You get my vote anyway!!

will let you know once updated site is up, should be the next couple of days.....
